CVE-2012-3039

Status: ModifiedHigh (7.1)—

Moxa OnCell Gateway G3111, G3151, G3211, and G3251 devices with firmware before 1.4 do not use a sufficient source of entropy for SSH and SSL keys, which makes it easier for remote attackers to obtain access by leveraging knowledge of a key from a product installation elsewhere.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
